C) The molecules of a gas are much further
apart than those of a solid.
A gas is easily compressible while most solids are incompressible because the molecules of gas are much further apart than those of a solid.
What are gases?Gases is one of the four fundamental state of matter.
Gases can be defined as phase of matter that neither have fixed shape nor have fixed volume.
The molecules of gases are far apart from each other as compare to other phases of matter.
The change in properties of volume is known as compressibility and those fluid whose volume changes are known as compressible fluids or gases.
The fluids which does not compressed or expanded and its volume remain constant are known as incompressible fluids or gases.
Thus, gas is easily compressible while most solids are incompressible because the molecules of gas are much further apart than those of a solid.

Answer:
Conducting experiments and using the scientific method.
Explanation:
Scientists (and other people) test hypotheses by conducting experiments. The purpose of an experiment is to determine whether observations of the real world agree with or conflict with the predictions derived from a hypothesis. If they agree, confidence in the hypothesis increases; otherwise, it decreases.

What is the mass of an atom with 7 protons, and 7 neutrons?
Answer:
Explanation:
Nitrogen has an atomic number of 7 (Z=7) because it has 7 protons in its nucleus. Some nitrogen atoms have an atomic mass number of 15 (A=15). A is the number of neutrons plus protons in the nucleus. However, we already know that there are 7 protons.

What is a measuring cylinder?A Measuring cylinder, a graduated cylinder, a cylinder measuring, or a mixing cylinder is a part of various laboratory materials that are used for the measurement of the volume of liquids, chemicals, or solutions during laboratory work.
Graduated cylinders have more precise and accurate measurements than the common volumetric flasks and beakers used in the laboratory. These are of various volumes ranging from small to big.
These graduated cylinders are also used for the determination of displacement. It is a measurement of the change in a volume of water when some additional materials are added to it.
This means that a graduated cylinder can be used for the determination of solid materials by taking the difference between the initial volume of water and the new volume of water.
Therefore, in this case, the mark represents a volume of 25ml.

water is 11.19% hydrogen and 88.1% oxygen by mass. Lake superior contains about 1.2x10 kg of water. what mass of hydrogen is contained in lake superior
Answer:
mass of hydrogen in lake = 11.19% of 12
= 1.3428
check if question is correct or not
Explanation:
Water is 11.19% hydrogen and 88.1% oxygen by mass. Lake superior contains about 1.2x10 kg of water the mass of hydrogen is 1.32 kg
What is mass?Mass is defined as a unit of measurement that describes the amount of matter that makeup an object.
It can also be defined as quantitative measures of inertia, fundamental properties of all matter. It is a dimensionless quantity.
As given 11.19% hydrogen is present in 1.2 x 10 kg
So, the mass of hydrogen = 11.198 % of 1.2 x 10 kg
= 11.19 / 100 x 12
= 1.32 kg
Thus, water is 11.19% hydrogen and 88.1% oxygen by mass. Lake superior contains about 1.2x10 kg of water the mass of hydrogen is 1.32 kg.

What is replacement reaction ?One element in a molecule is replaced by another in a chemical reaction known as a single-displacement reaction, sometimes referred to as a single replacement reaction or exchange reaction.
One element in a compound is switched out for another in a single replacement reaction. In a double-replacement process, the anions or cations of two ionic compounds are switched. In a double-replacement reaction known as a precipitation, a solid precipitate is one of the products.
One ingredient replaces another comparable element in a compound in a single-replacement reaction.

how do I solve for V1 in this equation
Answer:
[tex]V_{1} = \frac{P_{2}V_{2}T_{1}}{P_{1}T_{2}}[/tex]Explanation:
[tex]\frac{P_{1} V_{1}}{T_{1}} = \frac{P_{2}V_{2}}{T_{2}}[/tex]
First of all cross multiply
That's
[tex]P_{1}V_{1}T_{2} = P_{2}V_{2}T_{1}[/tex]
Next divide both sides by [tex]P_{1}T_{2}[/tex] in order to isolate [tex]V_{1}[/tex]
We have
[tex]\frac{P_{1}V_{1}T_{2}}{P_{1}T_{2}} = \frac{P_{2}V_{2}T_{1}}{P_{1}T_{2}}[/tex]
We have the final answer as
[tex]V_{1} = \frac{P_{2}V_{2}T_{1}}{P_{1}T_{2}}[/tex]

Explanation:
hope it help ^_^
Mass is the most basic property of matter and it is one of the fundamental quantities. Mass is defined as the amount of matter present in a body. The SI unit of mass is the kilogram (kg). The formula of mass can be written as:
Mass = Density × Volume
The mass of a body is constant; it doesn’t change at any time. Only in certain extreme cases when a huge amount of energy is given or taken from a body, the mass may be impacted. For example, in a nuclear reaction, a tiny amount of matter is converted into a huge amount of energy, this reduces the mass of the substance.
There are various units for calculating mass, like, kilograms, grams, lbs, pounds, etc., but the SI unit of mass is "kilograms" or kg. Every unit of mass can be converted to other units by using a proper conversion formula without affecting the meaning and essence of the quantity to be measured.
